描述了纵向记录和垂直记录对比特性之间的互补规律。在纵向记录中，记录分辨率与记录层介质参数（厚度/spl δ /、矫顽力H/sub c/、剩余力B/sub s/）有显著的相关性。相反，在垂直重编码中，参数不决定分辨率。这种本质区别是由消磁的相反效果造成的。在原型设计过程中发现驱动器的读/写特性服从互补性。
Complementarity law between contrastive characteristics of longitudinal and perpendicular recording is described. Significant dependence of recording resolution upon media parameters of recording layer (thickness /spl delta/, coercive force H/sub c/, and remanence induction B/sub s/) in longitudinal recording is indicated. In contrast, the parameters do not govern the resolution in perpendicular recoding. This essential difference is caused by the opposite effects of demagnetization. Read/write characteristics in drives are found to obey the complementarity during prototyping.
